過すぎたるは及およばざるがごとし

expression

too much is as bad as too little; the last drop makes the cup run over

A classical proverb warning that excess can be just as harmful as deficiency. Often used to caution against overdoing something, even if it is good in moderation.

• 過すぎたるは及およばざるがごとしというから、勉べん強きょうも休きゅう憩けいもバランスが大たい切せつだ。

  As the saying goes, 'too much is as bad as too little,' so balance between study and rest is important.

• 親しん切せつも度どを越こすと迷めい惑わくになる。過すぎたるは及およばざるがごとしだ。

  Even kindness becomes a nuisance when overdone. It's a case of 'the last drop makes the cup run over.'
